SUPPLY-VALVE FOR FLUSH-TANKS.

No. 899,486. Specification of 7 Ap lication filed October 24 Letters Patent. Patented Sept. 22, 1908.

, 1905. Serial No. 234,220.

To all wlwm umay concern:

Be it known that I, Osman FQGLIDDEN, a citizen of the United States, residing at Grand Rapids, in the county of Kent and State of Michigan, have invented certain new and useful Improvements in Supply- Valves for F lush-Tanks and I dohereby declare the following to, bee. full, clear,;and exact description of the invention, such as will enable others skilled in the art towhich it ape pertains to make and use the same. p

My invention relates toimprovements in supply valves for flush tanks, and its object is toprovide a submerged valve not likely to get out of order; to provide such valve with a downward. discharge to prevent escape of water from the top of the tank in case the' valve should get out of order; to provide improved lever mechanism whereby thevalve 1s securely closed, and to provide the device with various new and useful "features, hereinafter more fully described and particularly oint-ed out in the claims, reference being bad to the accompanying drawings, in which:

Figure l. is a side elevation ofa device embodying my invention; Fig. 2. a plan view of the same; and Fig. 3. a detail in vertical-section of the adjustable closure.

Like numbers refer to like parts in both of the figures. i

1 represents a portion of the bottom of the tank; 2 a tube extending vertically through the said bottom, and to which the water su ply pipe is attached; 3 is an extension of t e tube 2, cilrved in an arc of about ninety degrees and terminating in ahead 4 open at the under side and provided with a detachable annular valve seat 5- surrounding a downward discharge opening, which opening is closed when the float rises, by means of a closure 6 mounted in a socket formed in a pivoted lever 7 and vertically adjustable by means of a screw 8. This lever 7 is pivoted at one end between lugs projecting laterally from the base of'the curved extension 3 and! at the other end is vertically movable, and o erated by a connecting rod 13 ivoted t ereto at one end and pivoted to t e float lever 11 at the other end. This float lever is pivoted at oneend'to an arm 9 extendingibeneath the lever 7 and having an annular portio -10 opposite the screw 8 to permit access to the same. To the outer end of the floatvlever 11 is attached a float 12, which rises as the tank is filled, and thus carries the end of the lever 7 upward and brings the closure 6 against the seat 5. The connecting rod 13 and the pivoted end of the lever 11 form a toggle lever and thus compound the leverage whereby the float exerts a very strong pressure to hold the valve in closed position. Thedischarge being downward, if the closure lever should be accidentally displaced, the water .Will be discharged into the bottom of the tank and will not fly over the top thereof as with a side or top discharge. The valve being submer ed, is liable to accumulate sediment, but'ieing devoid of any sliding or piston movements, it will not be obstructed,

ut will operate regardless of any sediment thereon.

Having thus fully described my invemion, what I claim anddesire to secure by Letters Patent is:

1. A supply valve for flush tanks, comprising a tube adapted to be inserted in a tank, a head on theinner end of the tube.

having a downwardly open valve seat, a lever pivoted at one end and extending beneath the valve seat, a closure mounted on the lever intermediate its ends, a rigid arm beneath the lever, a toggle lever between 'the end of the rigid arm and the movable end of the pivoted lever, and a float attached to the togg e lever.

"2. A supply valve for flush tanks comprising a tube a apted to be inserted through the bottom of e tank, an upward and curved extension t the tube a head on the tube and aving a ownwardly open valve-seat, a piv oted lever beneath the valve seat, a closure adjustablylmounted on the lever and engag- ,"ing the seat, a rigid arm beneath the lever, a

float lever (pivoted to the arm, a connecting rod pivote at its respective ends to the closure lever and the float lever, and a float attached to the float lever. y)

3. A supply valve for flushing tanks comprising a. tube ada ted to'be inselted, in the ottom of the tan an upwardliprojecting curved extension to the tube, a ead on the end of the extension and having a downward opening, a detachable annular valve seat in said opening, alever beneath the valve seat givoted to the base of the extension, a

l i l the valve seat, an adjusting screw in the lever, 1

rigid arm having an annular portion opposite the screw and extending beneath the lever; it float lover pivoted to the arm, a float on'seid lever, a connecting rod pivoted at its respective ends to said. levers and forming with the float lover, a toggle lever to operate the closure lover.
